| Abstract: | An electron paramagnetic resonance (E.P.R.) study on ammonium 9-molybdomanganate (NH4)6MnMo9O32.8H2O, has been carried out. The system has a Mn(IV) central ion and can be considered as a d 3 ion in a D 3 environment. The results are fitted to a spin hamiltonian with S = 3/2 and I = 5/2 which is due to 55Mn. The values of the spin hamiltonian parameters determined were  A ligand field theory approach has been taken in an attempt to interpret the observed zero-field splitting parameter. |
